COMBINATION WIRE-WORKING TOOL.

SPECIFICATION forming part of Letters Patent No. 777,126, dated December 13, 1904. Application filed April 18, 1904. Serial No. 203,653. (No modeh) To wZZ whom, it puny concern:

Be it known that I, ALVORD M. MOLERAN, a

' citizen of the United States, residing at Kancharacter for pulling staples and cutting,

stretching, and splicing wire.

The tool is especially adaptable for use in the construction and repair of wire fences; and it consists in the novel construction, combination, and arrangement of parts hereinafter described, and pointed out in the claims; In order that it may be fully understood, reference will now be made to the accompanying drawings, in which- Figure 1 represents a sideelevation of the tool in an open position and the outer ends of the levers broken away. Fig. 2 is a detail perspective view showing the two circular heads embodying the improvements. Fig. 3 is a longitudinal section taken on line 111 III of Fig. 1.

lie carrying out the invention I employ two circular heads 1 and 2, each of which is provided with a pair of diametrically oppositely disposed segmental splicing-jaws 3, a clamping-jaw 4 at its inner side, and a staple-pulling jaw 5 at its forward central portion. The circular heads are reinforced with a series of equally-spaced segmental ribs 6, leaving intervening recesses 7 for the reception of the segmental ribs on the opposing heads when the latter are pivotally secured together by a transverse pin 8, extending through the cen-.

tral portions thereof. Recesses 7 are wider than segmental ribs 6 in order to permit the operation of the latter when the tool is opened or closed. Ribs 6 are provided with peripheral flanges 9, the inner edges of which overlap and protect the narrow portions 10 of the opposing heads, as shown in Fig. 3. Edges 13 of ribs 6 are tangent to the splicing-jaws 3 v and clampingaws 4 for presenting a wlde bearingsurface to a wire when gripped by said jaws preparatory to splicing or stretch- .ing said wire, and thus prevent the latter from being severed by the narrow edges 1 1 15 of said jaws.

16 designates a centrally-disposed circular bearing formed inte ral with the inner surface of head 1 and provided with a concentric boss 17 adapted to fit snugly within circular recess 18, formed by an annular bearing 19, cast integral with the inner surface of head 2 and adapted to fit against the side of hearing 16.

Heads 1 and 2 have U-shaped recesses 20 extending inwardly from jaws 6 to bearings 16 17 for the reception of oppositely-disposed cutting-blades 21, removably secured in dovetail recesses 22 in the adjacent ribs 6, (see Fig. 2,) so they may be taken out and sharpened when necessary. Each head is provided with an arm 23, formed integral therewith adjacent to clamping-jaws 1, to which lovers 24 are securely riveted, each head being reinforced with a centrally-disposed circular boss 25 where pin 8 extends therethrough. When heads 1 and 2 are pivoted together and occupy an open position, the splicing-jaws and clamping-jaws therein register, so that a wire may be readily inserted between either pair of said jaws, and as the latter are segmental in form their oppositely-disposed tips 26 will engage and prevent the wire from slipping outwardly and becoming accidentally released before the jaws close thereon, as indicated by dotted lines, Fig. 1. Pin 8 is relieved of the shearing strain produced in firmly gripping and stretching a wire by boss 17 engaging the inner annular surface of bearing 19.

The cutting edges of blades 21 are oppositely disposed, as above described, and are arranged centrally between the outer sides of heads 1 and 2, (see Fig. 3,) so that the strain produced in cutting a wire will also be transferred to the contacting edges of bearings 16 19 instead of exerting lateral pressure on said heads, as would be the case if they operated in the same manner as a pair of shears, and consequently pin 8 will be relieved of all ten sile strain.

In splicing a wire the broken ends of the latter are firmly gripped by the oppositely disposed gripping-jaws 26 and the tool is rotated in a horizontal plane, which movement twists the ends of the wires together and takes up all slack in the latter. In pulling staples from a post the staple is gripped by the pointed terminals of jaws 5 and readily withdrawn from the post by pressing downwardly on the levers and permitting the curved edges of circular heads 1 and 2 to bear against the post, and thus act as a fulcrum.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A tool of the character described, having a pair of heads pivotally secured together provided at their forward portions with U-shaped recesses and at their adjacent sides with dovetail recesses, centrally-disposed cutting-blades secured in the dovetail recesses and projecting into the U-shaped recesses, wire-gripping jaws extending transversely through the heads and communicating with the edges of the latter, and levers secured to the heads.

' 2. In a tool of the character described, a pair of circular heads pivotally secured together, equally-spaced segmental ribs formed integral with the adjacent sides of the heads fitting in recesses, provided in said heads for their reception and operation, segmental jaws communicating with the ribs and the peripheries of the heads, and levers secured to the heads.

3. In a tool of the character described, a pair of circular heads pivotally secured together, equally-spaced segmental ribs formed integral with the adjacent sides of the heads fitting in recesses, provided in said heads for their reception and operation, peripheral flanges on the ribs overlapping the edges of the opposing heads, and levers secured to the heads.

4. In atool of the character described, a pair of heads pivotally secured together having recesses in their adjacent sides, segmental ribs formed integral with the adjacent sides of the heads fitting loosely in the recesses, and means for operating the circular heads.

5. A tool of the character described, comprising a pair of heads pivotally secured together, a centrally-disposed circular bearing formed integral with the inner side of one of said heads, a boss formed concentrically on said bearing, an annular bearing formed integral with the inner side of the opposing head adapted to fit against the circular bearing and having a recess for the reception of the boss, levers secured to the heads, wire cutting and gripping members on the heads, segmental ribs formed integral with the adjacent sides of the heads fitting in recesses provided in said heads for their reception and operation, and peripheral flanges on the ribs overlapping the edges of the opposing heads.

In testimony whereof I afiix my signature in the presence of two witnesses.
